But only if the above runs in batch mode, right?

And as I wrote elsewhere, I don't understand why being able to read
from stdin like it's a sub-process would be so much better than
actually using a network process.  We could introduce such a feature
for the batch mode, but it would mean serious complications, and I
just don't see the justification for that.
